摘要： An internal combustion engine includes a combustion chamber defined by a cylinder, a piston defining a piston top, a cylinder head with an intake port and an exhaust port, and a corresponding intake valve and an exhaust valve. The internal combustion engine further includes an intake manifold for supplying air to the combustion chamber and an exhaust manifold for drawing exhaust gas from the combustion chamber. The flow dynamics of the internal combustion engine are improved by including textured surfaces on one or more of the piston top, the cylinder head, the intake valve, the intake port, the exhaust valve, the intake manifold, the exhaust manifold, or the fuel supplier. The textured surface may include indentations, protrusions, or combinations.

摘要： A throttle plate for use with internal combustion engines comprised of a relatively thin piece of material so that installation of the throttle plate between the carburetor or throttle body and intake manifold of a vehicle does not require additional brackets or components to correct throttle cable linkage length or geometry. The throttle plate comprises a plate having apertures to accommodate pre-existing connectors and a perimeter that corresponds to connections between, and the geometry of, the carburetor or throttle body and intake manifold. The plate fits between the carburetor or throttle body and intake manifold and defines at least one airflow hole corresponding to the airflow path in the carburetor or throttle body. If there are multiple airflow paths between the carburetor or throttle body and intake manifold, then there will be multiple airflow holes. One or more vanes integral with the plate extend radially from the perimeter of each airflow hole toward its center. The plurality of vanes can be a variety of shapes, including helical and inclined, and extend into the airflow hole only to the extent they work in proximity of the throttle valve(s) and do not obstruct operation of the throttle valve in the throttle body. As air flows from the throttle valve(s) through the throttle plate and into the intake manifold, the vanes redirect laminar airflow into turbulent airflow.

摘要： A device for use in an air intake path of an internal combustion engine to improve the engine performance. The device body has a top surface, bottom surface and at least one air passage defined about an axis from the top surface-to the bottom surface, containing a chamfer at each end. The upper portion of the passage surface contains a plurality of V-shaped veins about the axis of the passage. The lower portion of the passage narrows in diameter to a point equal to or greater than the vein extension in the upper portion. The lower portion also defines a grooved surface starting at it's beginning having a 60 degree slope edge and a flat bottom major diameter spaced in such a manner as to have a helical shape and to circumscribe the passage wall terminating prior to the end of the lower passage.

摘要： A connecting piece (1) is disposed between a carburetor (4) and an inlet channel (3) in an internal combustion engine of a portable handheld motor-driven work apparatus. The connecting piece functions to compensate for relative position changes between the engine and the carburetor (4), is made of elastic material and includes an expansion fold (5) for compensating for changes in position. The length of the expansion fold (5) is changeable from a collapsed to an expanded length. The expansion fold (5) subdivides the connecting piece (1) into a carburetor-end channel section (6) having a circularly-shaped cross section and an engine-end channel section (7) having a cross section departing from the circular form at the end facing toward the engine. The connecting piece (1) has a constant flow cross section over its entire length when the expansion fold (5) is collapsed.

摘要： An elastic connecting piece (1) is mounted between a carburetor (4) and an inlet channel (3) of an internal combustion engine (2). The engine (2) is especially an engine of a portable handheld motor-driven work apparatus such as a motor-driven chain saw, cutoff machine or the like. The connecting piece (1) includes a peripherally extending expansion fold (5) arranged between its ends in order to compensate for changes in length. The expansion fold (5) subdivides the connecting piece (1) into a carburetor-end section (6) and into an engine-end section (7). The annular gap (28) of the expansion fold (5) can be bridged by a seal lip (8). The connecting piece (1) includes a peripherally extending seal seat (9) of axial length (g) in the region of the expansion fold (5). The seal lip (8) can be placed in seal-tight contact with the seal seat (9) and substantially closes the expansion fold (5) fluid tight to the interior space of the connecting piece (1).

摘要： An elongated fuel-air bypass is connected between an outlet port of a fuel-air mixing device and an inlet port of an intake manifold of an internal combustion engine. The elongated bypass apparatus includes an elongated bypass conduit formed of a thermally conductive material and which has sufficient length, exterior surface area and thermal conductivity to enable it to cause liquid fuel introduced through the fuel-air mixing device to change from a liquid state to a gaseous state prior entry into the one or more cylinders of the internal combustion engine. Turbulence creating mechanisms, such as venturis or baffles, are provided in the elongated bypass conduit for creating turbulence in the fuel-air mixture flowing therethrough. An after-air supply tube is provided to supply after-air near an upstream end of the fuel-air bypass conduit, and is controlled by an after-air valve to provide for a lean fuel-air mixture. Also provided is a liquid additive system for supplying water and/or alcohol into the fuel-air bypass conduit. A start-up fuel injection system is provided to inject a burst of fuel into the fuel-air bypass conduit at initial start-up of the internal combustion engine. At least one reparticulation reservoir is provided in the bottom of a portion of the fuel-air bypass conduit in order to enable quick start-up of the engine after flooding.

摘要： An intake manifold and cylinder head intake passageway for an air-cooled internal combustion engine. The manifold is substantially S-shaped and generally vertically oriented and communicates a carburetor having a horizonal bore with an overhead valve cylinder head having a horizontal intake passageway located at an elevation above that of the carburetor. The manifold has a turbulence inducing ridge at the entrance from the carburetor and the cylinder head intake passageway has a similar ridge at the entrance from the manifold. Each elbow bend in the manifold and in the cylinder head passageway is provided with a flat area at the outside curve of the bend which prevents puddling of fuel in the arcuate section of the bend and which causes any fuel which collects there to be spread out in a thin film which is then reintroduced into the air stream by a wedge-shaped ridge transverse to the flat area and rising therefrom to a ridge peak.
